Despite its association with health problems, cholesterol is something the body needs. Cholesterol is necessary to make certain hormones. Cholesterol also plays a role in making some of the substances required to digest food.
Cholesterol travels in the blood in the form of lipoproteins, which are tiny molecules of fat wrapped in protein. From the liver, the excess LDL cholesterol is removed from the body. The liver plays another key role in cholesterol. Most of your cholesterol is made in your liver. The rest comes from the food you eat. Dietary cholesterol is found only in animal food sources, such as eggs, meat, and poultry.
High LDL levels may be lowered by medications, such as statins, as well as regular exercise and a healthy diet. In fact, lower cholesterol is better than high cholesterol most of the time. While the exact effects of low cholesterol on health are still being studied, researchers are concerned about how low cholesterol appears to negatively affect mental health. An Duke University study of healthy young women found that those with low cholesterol were more likely to have symptoms of depression and anxiety.
Researchers suggest that because cholesterol is involved in making hormones and vitamin D, low levels may affect the health of your brain. Vitamin D is important for cell growth.

From the standpoint of heart health, the total cholesterol level can never be too low. This, in turn, increase your risk of atherosclerosis hardening of the arteries , heart attack, and stroke. HDL functions as an antioxidant, preventing arterial damage caused by other lipids. If the HDL is low a condition referred to as hypoalphalipoproteinemia , the loss of the antioxidative effect may not only promote but accelerate plaque formation.
There are many reasons why your HDL may be low. Chief among these is a high-carbohydrate diet. Other factors associated with low HDL levels include:. While a low-fat diet is not seen to contribute significantly to chronically low HDL levels, malnutrition can.
While it would be fair to assume that a low LDL is a good thing, there are rare circumstances in which chronically low levels may increase your risk of certain diseases.
LDL is a lipoprotein, whose role it is to deliver lipids to every cell in the body. Cholesterol is a critical component of cell membranes, serves as a brain antioxidant, and is used by the body to create the hormones estrogen, progesterone, and testosterone.
Chronically low LDL levels may impair brain and hormonal activity and increase the risk of hypobetalipoproteinemia , a condition linked to depression, cirrhosis, preterm birth, hemorrhagic stroke, and certain types of cancers.
Similarly, abnormally low LDL levels during pregnancy may trigger hormonal imbalances that contribute, at least in part, to premature birth. With that being said, hypobetalipoproteinemia is often caused by cancer, liver disease, severe malnutrition, and other wasting disorders.
It may be in some cases, but not others. It is often difficult to manage low cholesterol with anything other than diet or lifestyle.
